I'm looking for a way to execute a MEL script that determines weather a file is read-only and warns the user if they are currently viewing a file which they will not be allowed to save.

I know how to do this, except for the part where the script is run whenever a file is opened.

I saw in the documentation that there is a scriptNode that can be attached to a file to run a command when the file is opened, but I don't want to make people attach a new node for each new file they make.

Is there any way that this can be done transparently? For instance, perhaps by adding something to a config file somewhere--all files will run a certain script on startup. Does anyone know of a way to do this?

Thanks all!

Not an elegant solution nor will be what you are looking for but you could create a mel script that uses the OpenFileDialog command, do a check on the file selected to see if it's Read/Write, then spit back some output or a popup that alerts the user (which you probably already have). Take that script and save this as a button in your shelf.

So everytime someone opens a file, they will need to use the button to check if the file is read/write or not. :(

Hi,

Either put something in everyone's userSetup file to run something on fileLoad (scriptJob) or use the scriptNode.

As far as I know the "Open" menu command is in fact already somesort of a script since it's not just opening a file, but also adding the item to the favorites list using mel. Just check the script editor.
So just do a search in the default maya mel files, I'm pretty sure you'll be able to find the procedure for opening files right there.

Thanks for all the helpful responses everyone!

I ended up going with a scriptjob in the userSetup.mel that our art team shares. I was a fool not to think of a scriptJob earlier, but I don't have much experience with them.

For the curious and helpful, the final solution looks like:

//this will warn the user if they are opening a read-only filescriptJob -event "SceneOpened" "source ReadOnlyWarning.mel" -permanent;
